In this chapter, we will discuss how our concept of temporal history has also been expanding. Human history is based on generational oral and written accounting of events of the past. The oldest reliable written history is probably by the Chinese, who can trace written records back to the ...
During the early period of the earth's history, the weather on earth apparently fluctuated between bright sun and showers. In recent times, however, the mountains and valleys on land and under water have had a great influence on the earth's weather. They effect the movements of the thin ...

This lambda176Lu value indicates that Earth's oldest minerals were derived from melts of a mantle source with a time-integrated history of depletion rather than enrichment. The depletion event must have occurred no later than 320 Myr after planetary accretion, consistent with timing inferred from ...

the Earth's early planetary differentiation. A major outstanding question in the Earth sciences is whether the volume of continental crust today represents nearly all that formed over Earth's history or whether its rates of creation and destruction have been approximately balanced since the Archean. ...
